Greta Van Susteren and Gretchen Carlson Feud on Twitter

Gretchen Carlson took aim at former Fox News colleague Greta Van Susteren, slamming Van Susteren for not initially believing the sexual harassment allegations she made against the late Fox News chief Roger Ailes.

The online quarrel began Friday after Van Susteren tweeted criticism of ABC News.

True but what about when u called me a liar 24 hours after my story broke? U knew no #facts. You were someone I had always admired & heralded every time u came on my show. And u are a lawyer which made it so outrageous. https://t.co/DxJAXsyhyl
